Title: Method of automatically changing path of sewage according to ph value
Inventor: TSUCHIHIRO MICHIO
IPC: E03F3/00
Filed: 1993-01-18
Abstract: PURPOSE:To change the path of sewage automatically by a method wherein a layer formed of super water-absorptive fibers is provided so that it interrupts the sewage flow in a main sewage flow passage and sewage water whose pH value varies is caused to flow through the flow passage having a branch in which a valve opened and closed by pressure is provided on the upstream side of the layer. CONSTITUTION:Super water-absorptive fiber non-woven cloth 1 is placed in a static state in a sewage pipe. A branch pipe having the same inside diameter is connected on the upstream side of the super water-absorptive fiber non-woven cloth 1. A pressure valve 2 is attached to the inlet of the branch pipe. Sewage water having a pH value approximately equal to neutrality flows from A and when the sewage water is brought into contact with the super water-absorptive fiber non-woven cloth 1, water is absorbed by the super water-absorptive fiber non-woven cloth 1 and gaps between fibers disappear, whereby water is stored at a part D. The pressure valve 2 is opened by the pressure and the sewage water flows to a part C. Further, when sewage water having a pH value of 1-3 or 11-13 flows from the part A, since the amount of water absorbed is small, the sewage water flows through the super water-absorptive fiber non-woven cloth 1 to the part B.

Title: Multiplier
Inventor: TAKAHASHI HIROMASA
IPC: G06F7/533
Filed: 1988-01-14
Abstract: PURPOSE:To accelerate the rise of the output signal of a decoder by raising up previously the output voltage level of the decoder in accordance with the change of the input signal of the decoder in a booth. CONSTITUTION:The pulses are produced to an N2 from pulse generating circuits 1-3 via a NAND gate 5 when at least one of inputs Y0-Y2 has a change. These pulses function to turn on transistors T1-T3 and to raise the voltage levels of outputs X0-X2 up to an intermediate level. As a result, the delay of the rise is avoided for the output signal of a decoder despite presence of many multiplication cells connected to the outputs X0-X2 since these outputs X0-X2 change after the electric charge is supplied to the load capacities connected to said outputs X0-X2.

Title: Manufacture of semiconductor device
Inventor: SHINPO MASAFUMI
IPC: H01L21/8247
Filed: 1988-01-14
Abstract: PURPOSE:To apply a dry etching technique to an etching process for an insulation film between polysilicon films which are formed on the first polysilicon film, by etching the first polysilicon film in such a way that the shape of each side wall becomes taper-like. CONSTITUTION:The first photoresist 4 is shaped into a desired form on the first polysilicon film 3 which is deposited on an element isolation layer 2. Polysilicon film etching in the above photoresist is carried out so that each side wall of the first polysilicon 3 may become taper-like. Thus, when an insulation film 5 between polysilicon films which is formed on the first polysilicon film 3 is etched, a dry etching process may be employed and then, the process by dry etching becomes a very useful method. This keeps the insulation film 5 between polysilicon films from entering into the inside beyond the width of a polysilicon gate.

Filed: 1994-01-25
Abstract: PURPOSE:To improve a phase noise from a synthesizer in a phase-locked type frequency converter which performs the frequency conversion of an input signal and simultaneously outputs it by making phase-lock with a reference signal. CONSTITUTION:A phase difference detecting means 2 detects phase difference between a signal to which the frequency conversion is applied and a frequency variable reference signal from a reference signal generating means 1, and an oscillation means 3 oscillates a signal of frequency in accordance with detected phase difference. A phase-locked loop oscillation means 4 receives the output signal of the oscillation means 3 as a phase comparison reference signal. and performs phase-locked oscillation by a loop including a frequency division means 4a, and outputs it to a frequency conversion means 5 as a local oscillation signal.
